'To all whom it may concern."

Be it known that we, JOHN F. RUDE and JOHN WVuSMrrrI, citizens of the United States, residing at Liberty, Union county, Indiana, 5 have invented a new and useful Improvement in I\Ianure-Sprea lers, of which the following is a specification.

Our invention relates to manure spreaders of the class wherein the material is distributed from wagon by means of a rotating toothed cylinder, and the objects of our improvement are to provide a distributing cylinder or beater with a series of alternating rows of teet which are angularly disposed toward its ends and which overlap each other at, their adjacent ends; to provide means for moving the center of the load laterally and toward the endsof the heater for distributing it more evenly to provide means for preventing the material from being delivered in bunches; to provide means for finely graduating the movement of the feeding carrier through a wide range of speeds; to provide means for adjusting the throw of the pawls both independently and simultaneously and to provide simple and durable construction of parts together with facility of operation and efliciency of action.

These objects are attained in the following described manner as illustrated in the accompanying (.lrawings, in which2- Figure 1 is aside elevation with parts broken away of a manure spreader embodying our improvements; Fig. 2, a rear elevation; Fig. 3, a sectional view extended longitudinally through the slotted arms ol' thepawl and ratchet mechanism; Fig. 4, a plan of the pawls with parts in section, and Fig. 5, an elevation of the bracket guide for the pawls.

In the drawings, 1 represents the rear axle,

2 the traction wheels, 3 the body, 4 the carrier shalt, 5 the ratchet wheel thereon, and 6 the carrier, all constructml and arranged in the ordinary manner.

The beater shaft 7 journaled on the rear end of the body is provided at one end with oppositely disposed eccentrics 8 and at the other end with a sprocket wheel 9 which communicates with the axle in the usual manner by means of a chain (not shown).

Said shaft is also provided with a webbed head ll. at its middle point and with similar heads 12 and 13 nea its respective ends.

The beater slats are formed in two sets one set connected to each outer head 12 anc and 13 and alternately connected to the inner head ll these slats incline from the outer to the inner head forwardly in the direction of rotation so that their inner ends when approaching the load on the under side of the beater are in advance and when on the upper side ol the beater are in the rear of the outer ends.

The inner ends of the adjacent slats are extended a short distance beyond each other and also beyond the middle head 11, said slats are preferably formed with a convex outer surface and they are each provided with a series ol pins 15 which project there ,from on both sides of the middle head where by the number of pins in the middle zone of the beater are doubled for facilitating the spreading of the middle portion of the load which is usually the thickest.

Similar arms 16 each rovided with a slot 17 are mounted to osci late on a pivot 18 which is secured at a fixed point on the side of the body and in front of the ratchet wheel 5. The eccentrics 8 are connected with the ends of the respective arms by means of adjustable ccccntric rods 19. Similar bifurcated awls 21 straddle the res ective arms 16 am arc connectcd thereto ljy means of pins or bolts 22 which are movable in the slots 17. A bracket guide 23 secured to the body is formed with slots 24 through which the pawls are movably extended for main taining thcm in proper lateral position on the taco ol' the ratchet wheel 5, where they are yicldingly maintained by means of springs 33. Links 25 pivotally conncctod at one end with thc hcclsol' the respective pawls are provided with a series ol holes 26 at the othcr cnd whcrcby they are independently adjustable on the bell crank 27 by means of a bolt 28. Said lcvcr is l'ulcrumcd on the side of thc wagon body and conncctcd with a detcnt lever 29 by means ol an adjustable rod 3i. A projecting board 32 sccurcd to the side ol the body serves as a hood over the pawl and ratchet mechanism to protect it from dirt.

In operation, by rcason of the slats ol" the beater being alternately and also angularly 105 disposed from the center toward its ends in such manner that the rotation of the beater carries their adjacent ends in advance'ol' their opposite ends through a fixed axial plane of the beater, a more even and uniform distribution of the material is obtained. This arrangement of the slats distributes the resistance evenly instead of intermittently to theipower which actuates the beater. The extending of the series of pins in each slat beyond thecenter of the beater doubles the number of pins in the intermediate zone thereof where the load is usually the deepest on account of being heaped. tion of the slats in retreating helical lines to its direction of rotation and toward the ends of the beater tends to distribute the thicker middle portionot theloadlaterally toward the ends of the beater.

The pawls may be independently adjusted on the bell crank. lever by means of the links, that they may be moved or thrown either the same or different distances as desired by the oscillating arms. The detent lever serves to move the pawls simultaneously to more or less throw in any position of adjustment in relation to each other. The pawls may be so adjusted that the one with the longest throw will move the ratchet wheel one notch at a time while the other pawl will remain substantially inoperative. By increasing the throw of both pawls simultaneously when adjusted in this manner the one with the shortest throw will move the ratchet wheel one notch and the other will move it two notches thus making the combined action. of the pawls three notches. By further similar movement they will move the ratchet wheel. iive or other odd number of notches. When they are adjusted to move equal distances they will move the ratchet wheel either two or other even number of notches.

The finely graduated. movement of the ratchet wheel thus obtained is very desirable for changing the speed of the feeding carrier to correspond to the different stages in the discharge of the load.

Having fully described our improvement what we claim as our invention and desire to secure by Letters Patent of the United States l. in a manure spreader, a beater coming shalt, heads thereon, slats secured heads and extending alternately from he ends to points beyond. the middle line of the beater.

A manure spreader comprising a beat-er I provided with rows of teeth projecting therefrom in alternating lines from its respective The disposiopposite ends to points beyond the center thereof.

3. Ina manure spreader, a heater comprising pergipheral slats alternately disposed with overlapping adjacent ends and inclined in opposite directions respectively in a rearward direction to the direction of rotation of the beater.

4. In a manure spreader, the combination of a ratchet wheel, slotted arms fulcrumed at a fixed point,'means for oscillating them in respective opposite directions simultaneously, pawls carriedby the respective arms and engaging with the wheel, and means for independently adjusting the pawls on the arms.

5. A manure spreader comprising a ratchet wheel, arms pivotally mounted at a fixed point, pawls independently adjustable on the arms, hand actuated lever mechanism for adjusting, the pawls simultaneously on the arms, and means for oscillating the arms with the pawls into alternate engagement with the wheel.

6. In a manure spreader, the combination of a heater provided with oppositely disposed eccentrics, arms .respectively oscillated thereby, a ratchet wheel, a carrier actuated thereby, pawls coacting with the ratchet wheel and movable with the arms, means for independently adjusting the pawls on the arms, and means I or simultaneously changing the movement of the pawls.

- 7. A manure spreader comprising a ratchet wheel, arms pivotally mounted at a fixed point, pawls coacting with the wheel and. independently adjustable on the respective arms, means for oscillating the arms alternately in opposite directions, and means for yiehlingly maintaining the pawlsjn engagement with the wheel.

8. In a manure spreader, a heater provided with radially projecting teeth, said teeth being disposed. in alternating rows which overlap at their adjacent ends and are extended in respective opposite directions at a rearward slant to the direction of rotatio of the beater.

In testimony whereof witness our signatures at Liberty Indiana, this 25th day of October, 1907.
